Abstract
The electrostatic potential (EP) and electric field (EF) are calculated in the TON and CHA zeolites using periodic hybrid B3LYP, PBE, and PW91 functionals considering eight basis sets. Relative root mean square differences between the EP or EF values estimated between the different basis sets are evaluated in several domains available for adsorbate molecules in both zeolites. The EP is interpreted in terms of ionicity of the framework. ยฉ 2007 Wiley Periodicals, Inc. J Comput Chem, 2008

Use of a new atomic-nucleus model is proposed for relativistic atomic and molecular calculations; the atomic nucleus has a sphere of finite size and the electric field in the sphere is assumed constant. It is shown that for the basis-set expansion method based on this model, the Slater-type function
